To all 'whom t may concern.'

Beit known that I, ELI BASEL, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Water-Circulators, of which the following is a full and exact specification. Y l

The present invention relates to water circulating devices andaims to providey an improved water circulating means adapted more particularly to the cooling of internal combustion engines, especially of that type em loyed in automobile constructions.

ne object of the invention is to providel a water circulating Vdevice so constructed as to produce a circulation of the water by the action of a centrifugal impeller member arranged inthe water conduit.

Another object of the invention is to de-v vise an improved constructionadapted for automobile engines which will induce the proper water `flow at alltimes during the operation of the engine and independently of-its thermo-Siphon action.

It is also an object to produce a self-contained water circulatingvdevice in the form of an attachment which may be conveniently applied to an automobile engine as com-1 of order. j j

' vWith these general objects in view, the invention will now be desfrihn w'm reference to the accompanying drawing, illustrating one form of embodiment of the proposed improvements, after which thosefeatures'and combinations of parts deemed to be novel will'fbe severally set the appended claims.

'In the drawingforthV and defined in lFigure 1 is a face view of lone of the tubu-'i art of the device,

lar casings forming a v er member mountshowing the water impe `sion 15 ada casing 2, l the outlet extension 15. to manufacture, and not easlly gotten out'f bearing 11 `thereby coperating ed 'therein and the shaft of the latter in section;

Fig. 2 is a central Fig; 3 is an end elevation of an internal combustion engine, with parts broken away and showing the same equipped with a cooling system constructed in accordance with the present invention.

Referring to the said drawing in detail, this illustrates the entire housing of the invention `as comprising a pair of tubular Water conduit casings-1 and 2 arranged in communication with each other as shown in Fig. 2, andthe casing 1 bein formed with the intake extension 14 a apted. to make hose connection with the lower extremty' of the engine radiator,rand the casing 2 having the outletor delivery extented to make hose connection with the con uit 16 communicating with the water jacket of the engine A. The casing 1 is formed with an arm 19 extending in position for convenient attachment l.to one of longitudinal sectional view of the device; and

the engine bolts 18 having the nut 17 which is employed for clamping the arm 19 securely in place. The casing 2 is secured to the casing 1 by means of the cap screws 3, and the adjoining portions of the said casings are formed, as shown in Fig. 2, in

a manner cooperating to provide a chamber B for housing an impeller member 5. This member 5 is equipped with impeller blades of a width fitting snugly the width of said impeller chamber, and the latter is' formed with the curved Vand tapered swell B arranged to receive the water as driven under the centrifugal action of `said impeller blades, and to conduct the water on into the from which it is forced out through The impeller member 5 is carried by a shaft 4 which extends through the .impeller chamber -B and one end o the casing 1,

the opposite ends of said shaft being journaled, 'res ectively, inan elongated bearing 11 forme in the casing 1 an in a socket' :formed in the casing 2. The rovided with acollar 13 abutting e inner end of the bearing 11 and with they scket bearing 11'L for lpreventing any axial motion of the shaftfi whichy would `result in injury tothe side margins of the blades of the im ,shaft is against t peller member 5. A grease cup 9 is mounted 85 generated by 29" provided en -themengine shaft 32, from..

whichsaid v6 is driven by means of Thesamepulley ..128 also utilizedv for v driving theradiator tfan member 33, the

v ment by-said beltl 28.

. meansof a coil spring 21, 25 is attachedto the upper end of the arm 26 i' said Pulley ,15

the radiator, and

30 of which is also arranged in approximatelyf'the-plane of the pulleys 6 and 29 .in position for suitable driving engage- The fan member 33 isjournaled upon the 26- which isv pivoted at its lower en at` 27, upon the `en e, {so thatthe fan pulley 30 is thus aored a bodily movementl for taking-up the. slack-inI the belt 28.l This take up movementis automatically effected b one end of which adjacent the pulley 30, the opposite end of springvbeing attached to a plate member-22 which is Asecured to a part 24 of the en ne by means of a screw 23.

gli; will thus be apparent that a simple and eflicient construction and arrangement have been devised for carrying out the desired objects of the invention. l The principal objection tothe usual water circulating arrangement, which depends uponY .theheat theengine to produce the waterl'ow, lies in the fact that the circulation of the water must necessarily lag back until itsv temperature rises to a point where it has lost a large proportionof its efficiency as a cooling medium; and the unduly high vtemperatures,

results in boiling and evaporating away ofthe Waterj with serious inconvenience, necessitating stopping andfilling up v sometimes causing serious injury to the engine. With the present mprovements, so long as the engine is in operation, the device will be operated contin-f uously through the medium of the belt 28, and immediately the engine is started the watercirculation will begin, being of course independent of any thermo-Siphon action. since the circulationis maintained com' tinuoua and substantially constant, `the temperature throughout the water will also be practically uniform, and its eciency as a cooling medium is materiallyincreased as compared to that of water owing unevenly i1 linposition for-providing l .proper lubrication tothe bearing 11 of the y `peculiar mounting of the upper end of an arm Aor modifications as ma due to inadequate circulation, fre` quently .forming andthe temperature' of :which hasl been raised byv a-lagingaction The drive arrangement in t e -p rer'sent construction is also simplified, a singledrive operating both the fan and water circula member, and the h fan member and t e taining the belt at a proper tension.
